It's not something you can do. It's just something I wish vendors would
implement.
Today if dampening triggers, route is removed from RIB, which is
undesirable to many. If instead its local_pref was decreased, we would use
more stable routes (and propagate stable routes), but if it was last route,
we'd still have reachability when route is in table.
